In the period 2019-2020 at the Fruit Research & Development Station Bistrița observations have been made constantly in apple and other fruit trees orchards. As a consequence, besides the usual apple pests and diseases such as: the codling moth, the San Jose scale, woolly apple aphid, scab, powdery mildew and brow rot, new threatening pests were detected. They are a part of the Lepidopterae order and did not represent a major problem in the past. Male adults of Spilonota ocellana (eye-spotted bud moth) were caught on pheromone traps placed in a nearby plum orchard, for monitoring the flight of Cydia funebrana, in the years 2019-2020. The number of captures was 53 in 2019 and 159 in 2020 per trap. In 2019 the damage was sporadically encountered both on leaves and fruits but in 2020 the damage was significantly higher. On some apple cultivars the fruits were damaged up to 23,23%. Data suggest the need for control measures to be taken especially in the second part of the summer.
